Reconstruction of Jet Properties in Pb-Pb Collisions with the ALICE-Experiment

The study of the hot and dense medium created in heavy-ion collisions via the effect of parton energy loss is one of the major goals of jet and high-\pt\ measurements in these reactions. In particular the modifications of the longitudinal and transverse jet structure. Here the subtraction of the underlying heavy-ion event, as well as a precise knowledge of the background induced fluctuations of the reconstructed jet energy is required. We extract the modification of the near- and away-side jet yield in heavy-ion collisions at the LHC and present a detailed assessment of background fluctuations for jet reconstruction.
